I've got a 6 month old CKCS bitch who for the last 3 or 4 days has been cleaning herself more than usual, and needs to wee more than ususal. Yesterday she was sitting on the sofa with me and when she got up, there was a tiny dark brownish mark on the throw, she instantly started licking it as though she was trying to clean it away. Today she is very moopy and apart from a few sudden bursts of energy, she doesn't seem to be herself. For about 2 weeks now she has been rubbing herself up against one of her plush toys occasionally. At training on Tuesday the trainers dog was showing particular attending to her. Her vulva doesn't appear to be swollen and I haven't seen any other signs of blood. She barks at my husband for no reason, although she is still happy to sit on his lap and takes her toys over to him for him to play with her, and she is very "clingy" to me. Does it sound like she could be in season? If so, do I count yesterday as day 1? I don't want to take her to training classes if she's in season.
